Restrained eating style and weight status are highly correlated. Though both have been associated with an attentional bias for food cues, in prior research restraint and BMI were often confounded. The aim of the present study was to determine the existence and nature of an attention bias for food cues in healthy-weight female restrained and unrestrained eaters, when matching the two groups on BMI.
Attention biases for food cues were measured by recordings of eye movements during a visual probe task with pictorial food versus non-food stimuli. Healthy weight high restrained (n = 24) and low restrained eaters (n = 21) were matched on BMI in an attempt to unconfound the effects of restraint and weight on attention allocation patterns.
All participants showed elevated attention biases for food stimuli in comparison to neutral stimuli, independent of restraint status.
These findings suggest that attention biases for food-related cues are common for healthy weight women and show that restrained eating (per se) is not related to biased processing of food stimuli, at least not in healthy weight participants.
节制饮食的风格和体重状况高度相关。尽管两者都与对食物线索的注意力偏差有关，但在之前的研究中，节食和 BMI 往往是混淆的。本研究的目的是确定在匹配 BMI 后，健康体重的女性节食者和非节食者是否存在并存在对食物线索的注意力偏差。
通过视觉探测任务中的眼动记录来测量对食物线索的注意力偏差，该任务使用了图片形式的食物与非食物刺激。健康体重的高节食者（n = 24）和低节食者（n = 21）在 BMI 上进行匹配，以试图消除节食和体重对注意力分配模式的影响。
所有参与者与中性刺激相比，对食物刺激的注意力偏差都有所增加，而与节食状态无关。
这些发现表明，对与食物相关的线索的注意力偏差在健康体重的女性中很常见，并且表明节食（本身）与对食物刺激的偏向处理无关，至少在健康体重的参与者中是这样。
